Table name: ACCOUNTPRODUCTLINE
Display Name: Account Product Line
Keyfield: AccountProductLineId
Index: APL_AccountProductLineId

In AA [7.5.4]  roject Explorer, created a New Entity from an existing table.

Name of the entity is Account Product Line

Go ahead and save this, rebuild interfaces, etc. and this gives me an error.....

Try to RENAME the entity, and this is just a slow death.

ReAdded the New Entity, don't rebuild interfaces, etc. and try to Rename the Entity.....this aborts out as well.

Delete the Entity, Nuke Pave the dev files (have had bad experiences with AA and handling DELETED stuff).

In SLX LAN, rename the display name of the table to AccountProductLine and now all is well on the AA side of things.....

Moral of the story: don't have spaces, _, or an S on the end.....of SalesLogix tables and Display names.....
